SPECIFICATION forming part of Letters Patent. No. 269,471, dated December 19, 1882,

- Application tiled July 3, 1882. (X model.)

To all whom it may concern:

Beit known thatwe,OHARLEs M. SCHWARTZ and WILLIAM CARTER, both citizens or the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented certain new and useful Improvements in Permutation Door-Locks, of which the following is a specification. I

This invention relates to improvements in permutation door-locks, and has for its objects to provide novel means for loekinga door, whereby it is impossible to open the same except by those in possession of the combination on which the lock is set, and. to provide novel means for sounding a gong or bell in case any attempt is made to open the door by those not in possession of the combination on which the lock is set. These objects we accomplish by the mechanism illustrated in the accompany- 2Q ing drawings, in which- Figure 1 is an elevation of the lock with the front plate removed. Fig. 2 is a broken elevation of the lock with the front plate removed, and showing the alarm devices in position for ringing the bell. Fig. 3 is a section-on line w m, Fig. 1. Fig. 4 is an elevation of part of the lock, showing the bolt with the secondary bolt. Fig. 5 is an elevation of the permutation mechanism on line yy, Fig. 3. Fig. 6 is a perspec- 5 tive view of the inner details of the permntation mechanism.

A represents the door to which the lock is attached; A, the jamb to which the has-p is attached; B, the bolt of the lock; '13, the secoudary bolt; b, a bar connected to the bolt B; b, a cross-head on bar b, by means of which the bolt is drawn by the inner knob; 11 a spring operating the bar b.

O is a horizontal dropbar, supported on pins 0 0. Drop-bar O is connected to the secondary bolt B by a pin, d, passing through lugD and slot at in said bolt B.

. E represents a cam upon the inner end of the shaft of the outer knob; e, a pin on cam E,

5 operating in slot 6 in the end of the bolt B.

E represents a stop on cam E,engaging with hook F on the end of the connecting-bar F.

f represents the adjusting-lever by which the bar F is raised, so as to connect with the so stop E of cam E.

G represents a triplever connected with the horizontally-sliding rod G and pivoted at. g.

H represents a spring-hook, engaging with the hook it on the lower end of the 10d H, which carries the hammer of the bell.

I, represents a spring, acting upon. lug i on lower end of rod 1.

1 represents a spiral spring, operating the rod G. 7

J represents the casing of the permutation mechanism; j, the double inclined sliding blocks.

j represents connecting rods projecting through the door from the lock to the outside of the door. inclined planes L on one side, and also on the other side inclining in the opposite direction. The pins 0 rest upon the inclined planes Land pass through holes 0 in the casing J.

It is obvious that when the rods are drawn 0 out, carrying blocksj, the pins 0 will slide vertically downward through holes 0, resting upon the inclined planes L 'until they assume the same positionas the pins marked 0, Fig.

1. If any other of the rodsj be drawn out, thus sliding any other than the blocks'upon which pins 0 rest, the pins 0 will rise, sliding upward through holes 0 and resting upon inclined planes Ltill they assumepositions shown by dotted lines, Fig. 1.

It will be seen that it the operator pulls the proper rod j he will cause the pins 0 to drop, thus allowing the horizontal drop-bar O to fall. This carries the secondary bolt B down until the hook on upon its extremity engages with 8 the pin a upon bolt B. This position is shown in Fig. 4. The bolt will be readily drawn by the rotation of the outer knob when the parts are in this position.

S represents a spiral spring. coiled around the rodsj, inside the casing J, and upon releasing the rodsj said springs cause the blocks j to resume their former position, Figs. 1 and 3, thus raising the pins 0 and drop-bar O. This motion carries the secondary bolt B upward, so as to release it from engagement with pin it on bolt B. If the outer knob be turned when bolt B is up, the stop 0 on said bolt will engage with trip-lever G, causing the horizon- The blocksj are provided with 6 tally-sliding bar G to move, carrying the [00 hammer of the bell, until it assumes the posierated like any ordinary lock, and be readily spring-hook H, which engages and operates I hook it, thus moving the rod H, carrying the tion shown in Fig. 2, when the lug h, bearing down upon the hook H, forces it down and out of engagement with hook h, when the spring I, acting upon arm or lug z, quickly springs the rod back to its normal position, thus ringing the alarm-bell; When the adj usting-leverfis thrown up, carrying connecting-rod F, with hook F, up to position shown in Fig. 1, the rotation of the outer knob to the left will cause the stop E to engage with hook F,thns drawing the bolt B independently of the permutation mechanism and the secondary bolt B. \Vhen it is desired to lock the door from the outside, the operator, turning the knob in the opposite direction, causes the cam E to act upon hook F, forcing it down and out of en gagei'nent with stop E, when the bolt can only be drawn from the outside by means of the permutation mechanism of the lock. Wlren the connecting-bar F is up the lock may be opopened from either outside or inside without recourse to the permutation mechanism.

Upon the shaft of the inner knob is a pin, similar to pin 0 on cam E, which passes between cross-hcad b and partition 1t, and thus moves the bolt Bat every rotation of the knob.

It is obvious that the pins 0 0 may be inserted in any of the holes 0 O, and a large number of combinations obtained.

The number of sliding blocks and pins 0 0 may be increased at pleasure to multiply the combinations from two up, thus rendering the lock secure. WVe have shown six sliding blocks in the drawings.

We claim- 1. In a door-lock, thecombination, with the bolt B, of the drop-bar (J, operated by the permutation-pins 0, and the secondary bolt B, connected to the bar G,suhstantially as herein set forth. I

2. In a door-lock, the combination of the bolt B, the secondary bolt B, and the dropbarO with thepermntation mechanism,means for connecting and disconnecting the boltsB B, and the alarm mechanism adapted to be operated by the secondary bolt, substantially as described.

3, In a door-lock, the combination ofthe permutation mechanism, the bolt B,the drop-bar O, and the secondary bolt B with the outer knob having the; cam E, and means for connecting the permutation mechanism with and disconnecting it Rom the bolt B, substantially as described.

4. The combination of the bolt B, the permutation mechanism, the drop-bar O, the secondary bolt B, and means for connecting and disconnecting the bolt B and permutation mechanism, substantially as described.

5. The combination of the bolt B, the permutation mechanism, the drop-bar U, the secondary bolt B, and the pivotcdbar F, for connecting and disconnecting the bolt B and the secondary bolt Band permutation mechanism, substantially as described.

6. In a door lock, the combination of a main bolt, B, and permutation mechanism detachably connected together, with the secondary bolt B, the inner knob connected with the lat-- ter, and means to permit the drawing of the main bolt by the inner knob independent of the permutation mechanism, substantially as described.

7. The combination of the main bolt B, the secondary bolt B, the drop-bar 0, connected with the latter, the vertical pins 0 c, the inclined blocks j, and means for adjusting the blocks and moving the pins in avertical plane, substantially as described.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
